Librarian runs on your own machine — the client starts it, so there is no endpoint to ping. 362 installs a week from pypi. Last commit 10 Jul 2026.
Deterministic ebook-to-markdown pipeline with MCP tools to browse, search, and read your books.
Nothing serious here today
Today is the operative word: we check Librarian every 15 minutes and re-read its code on every release. Watch it and you find out the day that stops being true.
